顶架油缸性能测试试验台液压回路设计 摘要：目前在用井架均采用扒杆支撑、绞车滚筒拉绳起放和液压缸缓冲系统，劳动强度大，工序繁琐，且缓冲装置效果不好起放时存在严重安全隐患。关键字： Top shelf performance testplatformfor design of fuel tank Abstract: The present work on the derrick with a variety of support are used derrick, winch drum rope and hydraulic cylinder from the release buffer system, labor-intensive, tedious process, and the buffer effect is not good, since people who put serious time machine safety hazards. Replace the body with a hydraulic system, could well put the work of erecting a secure, easy and smooth, is worth promoting. In engineering, various derrick lifting support with a large telescopic hydraulic cylinder. Cylinder strength, stiffness and stability of the hydraulic cylinder derrick safety of the system plays a decisive role. Telescopic hydraulic cylinder with a large complex, expensive features, such as the current design of hydraulic cylinder and no fixed standard in engineering is very prone to burst, twisted, broken Yiji other failure modes, resulting in serious losses. Currently single, conventional methods can not meet the engineering strength check the actual needs of hydraulic cylinders combined with the practical need to work with different methods on strength, stiffness and stability are checked. Therefore, to test the hydraulic cylinder is of great significance. Keywords: derrick, hydraulic cylinder, hydraulic system, Test; strength check 目 录 第1章 绪论 1 1.1 概述 1 1.2 课题背景及国内外研究状况和意义 1 1.2.1 课题背景 1 1.2.2 国内外的研究现状 2 1.2.3 课题研究的目的和意义 4 1.2.4 课题研究的主要内容 6 1.3 设计内容 6 第2章 监测钻机的设计思想与方案的选择 7 2.1 概述 7 2.2 监测钻机的设计思想 7 2.3 监测钻机设计方案选择 10 2.4 监测钻机优越性与前景分析 13 第3章　监测钻机机械关键部件的选择与校核 15 3.1 概述 15 3.2 丝杠选择与校核 15 3.2.1 丝杠的选择 15 3.2.2 丝杠的校核 18 3.3 电机的选择与校核 19 3.3.1 电机类型的选择 19 3.3.2 电机型号的选择 20 3.3.3 电机的校核 24 3.4 导轨副的选择 26 第4章　监测钻机主要部件的设计与选择 28 4.1 概述 28 4.2 钻机机架部分结构设计 28 4.3 钻机承载部分钢板的选择 29 4.4 打孔钻的结构设计 30 4.5 探测窗口关键部件的固定与安装 31 4.5.1 光纤管在钻头内部管道的固定 32 4.5.2 蓝宝石镜片、凸透镜、平面镜的安装固定 33 4.6 平面镜固定架的安装 37 4.7 丝杠螺母副组合机构设计 3
